Chiefs Insider reported that defensive end Tyson Jackson and right tackle Ryan O'Callaghan were both downgraded to out on the injury report on Saturday. The two players were listed as questionable heading into the weekend.

Jackson, the No. 3 overall pick in the 2009 NFL Draft, injured his knee during Monday night's victory over the San Diego Chargers. O'Callaghan has been dealing with a groin issue.
